\nThis question contains information on how Numbas works, from the beginning of an exam to the end.

\nYour score for the question is the sum of your scores for each of the parts.
\n", "advice": "If this was a real question, there'd be a fully worked solution here. Instead, there's just this text to show where it would go.
\nAnd a picture of a numbat.
\n\nThis Numbas exam is presented in menu mode - you can choose to access any question in the exam from the menu.
\nExams that count towards course credit are normally presented in sequential mode - you work through a list of questions, and you can end the exam to lock your answers and see the feedback.
\nYou can move between questions however you like. It's a good idea to have a look at each of the questions in an exam before choosing the first one to answer.
\nIf the instructor has chosen to restrict your movement between questions, you'll be asked to confirm before leaving a question.

This means that for each attempt at the question, numbers and other information in the question are picked at random.
\nFor practice material, this provides an inexhaustible supply of questions on a particular topic, while for assessed material it means that you're very unlikely to be shown exactly the same question as another student.
\nInstructors set up the randomisation so that all possible versions of a randomised question are as difficult as each other.
\nAn example: this time, I have randomly picked the number {n}, which is {if(mod(n,2)=0,\"even\",\"odd\")}.

\nAnswers entered but not submitted are not marked: it's important that you submit each answer after entering it.
\nIf you submit an answer that is not valid - for example, if it's in the wrong format - Numbas will not mark it and will show a message describing what is wrong. Some kinds of errors, such as missing brackets, can be caught before you submit - you'll be shown a warning message next to the input box.
